15 Claims.

The invention relates to window regulators and refers more particularly to regulators for raising and lowering windows of closed motor vehicles.

, One of the objects of the invention is to provide 5 an improved window regulator which is strong and rigid and which may be economically manufactured. Other objects are to provide an improved means for mounting the lifter element of I the window regulator; to provide an improved 10 means for guiding the lifter element; to provide an improved construction of mounting plate, so arranged that it houses the irreversible drive mechanism of the window regulator; and to provide an improved construction of mounting plate having an integral portion forming an anchor for one end of the counterbalancing spring and a nut for use in securing the window regulator. to its support. These and other objects of the invention will become apparent from the following description, taken in connection with the accompanying drawingain which Figures 1 and 2 are respectively inside and outside elevations of a window regulator showing T an embodiment of my invention;

Figure 3 is a cross section on the line 3-3 of Figure 1;

Figure 4 is a cross section on the line 4-4 of Figure 1; Figure 5 is a cross section on the line 5-5 of Figure 3; t

Figure 6 is an inside elevation of a window regulator showing another embodiment of my invention.

The window regulator comprises the inside and outside mounting plates 1 and 2, respectively, the lifter element 3, the window counterbalancing spring 4 and the handle or crank shaft 5, which is adapted to actuate the lifter element through the irreversible drive mechanism 6.. The mounting plate 1 is preferably formed of cast metal and is die cast and the mounting plate 2 is preferably formed of sheet metal and is stamped from a. sheet metal blank. These two mounting plates are rigidly secured to each other at their ends and their intermediate portions are spaced apart a distance sufficient to receive the lifter element 3. In detail, the mounting plate 1 has formed integral therewith and at one end thereof the transverse projection 7, the end of which is reduced to receive the end portion of the mounting plate 2. The shoulder 8 formed upon the projection 7 by reason of the reduced end portion of this projection forms a stop engageable with the mounting plate 2 and this mounting plate is secured in this position by spinning or peening over the end of this projection to form the flange 9, the projection being preferably hollow to facilitate this operation. The other end of the mounting plate 1 is also provided with the transverse arcuate projection 10 which extends from the same side of the mounting plate as the projection 7 and the end face 11 of which forms a stop for the other end of the mounting plate -2. This projection 10 is preferably provided with the integral rivet projections 12, which are adapted to extend through the mounting plate 2 and to be headed over to secure the mounting plate in place. The mounting plate 1 is preferably longitudinally ribbed at 13 to make this mounting plate strong and substantially rigid. The mounting plate 2 further assists in making the construction strong and rigid, so that it will readily withstand the stresses and particularly those tending to bend or warp the mounting plates during the operation.

The lifter element comprises the gear segment 14 and the lifter arm 15 which are fixedly secured together, so that the one moves with the other. The gear segment is sleeved upon the 3 cylindrical portion 16 of the bushing 1'7 and the lifter arm is sleeved upon the portion 18 of the bushing having a polygonal external surface. This bushing is located between the mounting plates 1 and 2 and it is journalled upon that por- 35" tion of the projection 7 between these mounting plates.

The mounting plate 1 is also provided with the integral transverse projection 19 which is preferably axially aligned with the projection 7, 9'0 but extends from the opposite face of the mounting plate. This projection 19 is internally threaded at 20 to form in effect a nut to be used in conjunction with a threaded member, such as a screw, for securing the window regulator to the sheet metal lock board 21, which is shown in dotted lines in Figure 3. The external surface of this projection 19 is polygonal, it being square in the present instance, and is adapted to receive the correspondingly-shaped inner end portion of the spiral counterbalancing spring 4. The other end of this counterbalancing spring is adapted to be hooked over the transverse projection 22 which is preferably integral with the gear segment 14 and formed by a stamping 010- eration.

The mounting plate 1 is further provided with the integral cup-shaped housing 23, which projects from the same side of the mounting plate as the projection 19 and which terminates in 5 to 5 inclusive.

the reduced cylindrical flange 24 forming a relatively long bearing in which is journalled the handle or crank shaft 5. The irreversible drive mechanism 6 comprises the driving member 25, the driven member 26 and the resilient coil 27, all of which are enclosed within the housing 23 and, as shown, may be formed in the usual manner. The housing is formed with the internal annular shoulder 23 which is adapted to abut an end convolution of the coil 27 to serve in positioning this coil. The driving member 25. is driven from the handle or crank shaft and is an integral part thereof and has the fingers 28 which extend between the fingers 29 of the driven member 26. The coil spring 2? encircles these fingers and has the inturned ends 30, which are located between the fingers 28 and 29. The construction is such that the convolutionsv of the coil spring in the normal positions of the parts engage the inner surface of the housing 23and frictionally hold the parts from movement. However, these convolutions are moved out of frictional engagement with this inner surface upon actuationof the handle or crank shaft in either direction by reason of one of the fingers 28 engaging the adjacent inturned end 30 The driven member 26 is fixedly secured to the pinion 31, which meshes with the gear segment 1% and this pinion is journalled upon the pin 32, which has one end fixedly secured to the mounting plate 2 as by being riveted thereto and the other end extending axially within the driving member 25 and terminating near the cylindrical flange 24,

The mounting plate 1 further has the lateral projections 33 extending from its opposite edges, which are provided with the shoulders 34 preferably concentric with the axis of rotation of the lifter element and which are adapted to engage the side of the gear segment 14 near. its peripheral teeth. The mounting plate 2 is also provided with the depressed rib. 3.5. providing an arcuate. shoulder for engaging the other side of the gear segment near its teeth. These lateral projections 33 have the integral-transverse projections. 36 which are located on opposite sides of the housing 23. and which are. internally threaded at 37 to receive the threaded members, such as screws, used in securing the window regulator to the lock board 21.

The window regulator shown in, Figure 6. is designed to be mounted upon a wooden lock board and is constructed in essentially the same manher as. the window regulator shown in Figures. 1 However, the mounting plate 38 of this window regulator has its upper end portion 39 triangular shaped and provided. with the countersunk holes 40 for receiving the securing members. This mounting plate is further provided with the arcuate transverse flange 41 which is located between the housing 42 for the irre-. versible. drive mechanism and the spiral coun.-. terbalancing spring 43. and below the holes 40. to engage the lower edge of the lock board. and. assist in positioning the window regulator relative thereto.
